A common design pattern for developing software applications may include the “model, view, controller” pattern. For example, the model may include the data, the view may include how the user interacts with the software application, and the controller may include the middle logic or service layer that the view may call to interact with the model. Users (e.g., software developers) working on a software application using the above-noted model, view, controller pattern may be unaware if they make a change to the controller how it may affect various pieces of the view. Unit tests may be created to ensure that code in the controller layer continues to behave correctly.
